Scientific paper

We propose coordinated Chandra-HETGS (110 ksec), HST-STIS (6 orbits), and FUSE (50 ksec) observations of the the dMe flare star AD Leo to accurately measure for the first time the complete energy budget for coronal flares. FUV observations of the Fe XVIII 975 A and Fe XXI 1354 A coronal forbidden lines are needed from FUSE and STIS to determine the dynamical energy losses of the flares. HETGS spectra will be used to measure the temporal changes in the coronal emission measure, temperature, density, and elemental abundances. AD Leo is one of the brightest dMe stars in X-rays and flaring rate data suggests that we should see about 10 moderate (factor of a few) and one large (factor of 10-20 enhancement) flares in a 30 hour observation.
